Question

Масса 68см куб. меди равна 578г.Найдтье массу 112см куб.меди​

Answer 1

Выражение: 578 : 68 · 112 = 952.

1) 578 : 68 = 8,5 (г) - масса 1 м³ меди;

2) 112 · 8,5 = 952 (г) - масса 112 м³ меди.

Ответ: 952 г.

Answer 2

1)112:68=28/17

2)578•28/17=34•28=952

ответ:952

Answer 3

To find the mass of 112 cm³ of copper, we can use the information given about the density of copper. Density is defined as mass per unit volume, and it remains constant for a given material.

Given data: Mass of 68 cm³ of copper = 578 g

Now, we can calculate the density of copper using the formula:

Density (ρ) = Mass (m) / Volume (V)

Density of copper (ρ) = 578 g / 68 cm³

Next, we can use this density to find the mass (m) of 112 cm³ of copper:

Mass (m) = Density (ρ) * Volume (V)

Mass (m) = ρ * 112 cm³

Substitute the value of ρ (density of copper):

Mass (m) = 578 g / 68 cm³ * 112 cm³

Now, let's calculate the mass:

Mass (m) = 578 g / 68 cm³ * 112 cm³

Mass (m) = 8 g/cm³ * 112 cm³

Mass (m) = 896 g

The mass of 112 cm³ of copper is 896 grams.
